Square D 9007-A902 Pneumatic Timer

The Square D 9007-A902 Pneumatic Timer is a rugged panel‑mount timing relay in the Square D 9050 family designed to provide a precise on‑delay in industrial control circuits. It utilizes a 110–120 VAC coil (A010E family) and delivers an adjustable delay from 0.1 to 60 seconds with a single‑pole double‑throw (SPDT) contact arrangement (1 normally open, 1 normally closed) capable of switching loads up to 15 A at up to 600 V. This open‑enclosure timer is intended for panel installations and is typically mounted in harsh industrial environments, with dimensions around 2.64 in high × 4.02 in wide × 4.37 in deep and an operating temperature range of roughly 68–104 °F. Common applications include sequencing and timing for conveyors, pumps, and motor control circuits where a timed delay is required and rugged reliability is essential. A compatible snap switch replacement for this timer is the Square D 9007AO104, reflecting interchange within the Class 9050/9007 timing ecosystem. As part of the Square D line from Schneider Electric, the 9007‑A902 is used in industrial automation and control panels to achieve repeatable, time‑delayed operations in 0.1–60 second increments via the Type A pneumatic timer configuration.
